(237−126, 237, 697)-Net in Base 3 — Upper bound on s

There is no (111, 237, 698)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 126743 535431 531735 261443 312808 061134 190382 021243 728998 564027 471144 193483 229289 233299 319414 431378 240162 228809 582937 > 3²³⁷ [i]
